"Read the indictment. They are monitoring these forums (and much more), they looked how a guy called "altoid" mentioned SR very early on, he had registered that account with his real email (BTW, Theymos: how did they get the email through which he registered his btctalk account?). So they thoroughly monitored "Ross Ulbricht", and they realized he had the same interests of DPR - they wrote about the same books, liked the same videos... So they started to follow his moves... And they caught him.

There's some debate about how the arrest will impact the future of Bitcoin.

"There might be a sudden flash crash, but I cannot see this news dragging the price below $100. If you are computer literate enough to use Tor and Bitcoin, then you should be well aware that identical, and possibly better services are already in the pipe. This market is way too big to just leave on the table."

And some are actually welcoming the arrest, arguing Bitcoin's reputation will be improved if it is no longer associated with Silk Road, which largely trafficked in illegal goods.

"This may be good news since there is nothing holding bitcoins back from becoming mainstream anymore," ronimacarroni wrote.
